Yamaha 02r ver2 and scenes back up

Hallo everybody,
I have a small problem... I have almost finished all the scene memories on my Mixer yamaha 02r Ver2 and I'd like to back up some to clean up space.... The manual just trell me how to send stuff to a sequencer and how to get it back. The problewm is that I'm not sure of what I'm sendi out to logic and I'm totally scared to make mistakes and clean Memories without having a proper back up of all my jobs.... :sad: So please can somebody tell me how to do my back up and check it (Even just one scene at time) So I can relax a bit ?
Thanx a Lot
